A system monitor tracks the temperature of a chemical reaction. A user inputs an integer value for the temperature, temp (in ∘C^\circ\text{C}∘C), into the algorithm below.
1 temp ← USERINPUT
2 IF NOT(temp > 10) OR temp > 80 THEN
3 OUTPUT "Error"
4 ELSEIF temp > 10 AND temp < 40 THEN
5 OUTPUT "Low"
6 ELSEIF temp MOD 4 = 0 THEN
7 OUTPUT "Critical"
8 ELSE
9 OUTPUT "Optimal"
10 ENDIF
State one integer value that the user could input that would result in an output of "Optimal".
